I have my Postfix configured to require proper DNS resolution in both
directions. However, I have a situation that is giving me problems
perhaps due to multiple PTR records for the IP address. I am getting
the error:
450 Client host rejected: cannot find your hostname
When I 'dig' the hostname the IP address matches that of the server
making contact with my Postfix. When I 'dig -x' that same IP address,
among the many PTR records, the hostname used in the 'HELO' matches.
The from doesn't match but that is not what it is comparing, right?
Can someone tell me what might get going on here? I am running version
2.1.5 so perhaps that is part of the problem.
Thanks.
